---Problem Description---
FW
==

Firmware Revision : 00.36
Firmware Build Time : 20171118  
PNOR Build Time : 20171110      
CPLD Version : B2.91.00


Test case
======

146351: OP:System Stress_RAID1_Pegas 1.1_ZoemIO-24_KVM        
ZoemIO24  = PM8069 


For this test case, I created a raid1 in the KVM host using 2 SAS drives
which are controlled by the PM8069 onboard sas/sata controller .  I
rebooted my machine to complete my set up for other test cases which I
planned to run them together.  I then passed this raid1 to a guest.   In
the guest, as soon as I  su - to htx,  these messages appeared on the
SOL of the guest

As a side note.   There was no error when raid1 was created and after I
rebooted this machine

The fix was pushed upstream. Please note that there are now 2 patches
instead of one: one from Paolo Bonzini and the one I've sent. We need
both.

The patches follows:

https://github.com/qemu/qemu/commit/2343be0d7ee8a6e02c2bf99d0243492085c8d399
https://github.com/qemu/qemu/commit/29e560f00e2bc1b5731c8276031aaf192de55d9d

Thanks,


Daniel

Without the previously mentioned patches, the system cannot pass a RAID volume 
on the primary disk controller to KVM guests.
